Cancer a way of controlling the population?

I was listening to a conversation two of my coworkers were having the other day about government control and whatnot, and how scary it is getting. Cancer is obviously a major killer worldwide, and as the population in the United States is in abundance of the elderly, one of them suggested that there are indeed cures for cancer, and that they simply aren't provided as a way to control population in the U.S. What are your thoughts on this reddit?

Dude, if you really want to be scared of the government using diseases to control the population, look into Plum Island. Several diseases, including Lyme disease, have hit the human population that lives near the island pretty hard.

When I hear stuff like this I feel bad for people. The earth is big enough for WAY more people then we have now. It would be pointless to have population control when (I think) we're suppose to even out at around 10-14 billion people anyways.

Geographically it may be large enough, but judging by our horrible chauffeur record, we are driving this planet straight to global destruction. The last thing we need is another 7 billion people screwing things up. A cure for cancer would destroy this planet in no time.
